The latest curtin now does package dep checks during installation
which may install and enable things like lvm2 and mdadm. These
packages trigger running daemons which prevent the unmounting of
filesystem when building the installer image. Resolve this by
re-implementing curtin's [un]disable_daemon_in_root functions.
Update runinstaller to use 3 spare disks as virtio to enable
raid testing.

Make sure we continue to use 1M alignment, this helps
parted shift things around properly. Don't reserve
space for root in installer image since it's read-only.
Add some fudge factor to the root image to allow for

The size of the rootfs fluxuates and sometimes does not fit in the
pre-allocated sizes. Instead, calculate the size needed for the
rootfs read-only partition (+ 100M padding) and use the remaining
space for the overlay partition as it's needed when the install
image updates it's apt repository.

Speed up install time by pre-installing required curtin packages
in the installer image. Do this by optionally exploiting a
curtin feature which handles preparing the target for installation
of services that we don't want running during the image build.
Fallback on simple apt-get install but filter out daemon services
as this will break the image build.

Instead of packing up curtin via source, build a
deb from the source and inject that into the installer.
This also means we always are consuming an 'installed'
curtin (aka /usr/bin/curtin).

Instead of tracking many directories, we'll use only one

overlayfs changed mount options between different kernel versions.
In some cases, an Ubuntu release may have a different kernel than
what was included during the release, so instead use the version
included in the module itself to determine what parameters to pass
when mounting.

We can't use curses_display with an external event loop (tornado). The good
news is that we don't have to. Instead we switch to using agetty to bypass
login, specify the installer and options to execture. This also handles
respawning the installer and works both on serial and without.
